2 have invented certain new an'df/luseful' Improvements in Apparatus for Merging Milk and Butter; and I do hereby declare the following to be .a full, clear, and exact descript1on of the invention, such as will enable others skilled in the art to which it appersurrounding body of hot water that the capacity of the vessel containing the water .must be so accurately proportioned to the vessel in which the milk and water are commingled, that with apredetermined temperature of the surrounding body of water, heat units will be delivered to the butter and milk in suficient quantity and at such a rate as to cause meltingv of the butter only as rapidly as it will take up the milk. In other words, extreme care must be exercised in proportioning the different parts of the apparatus to insure the changing of the temperatuiwas of the butter and milk both at the proper rate and at the proper degree.

The object of the invention is not only to provide an apparatus embodying the broad principles necessary for efiicient practice of the-process, but a specified mechanical structure which will be cheap of manufacture and durable so that the article may be placed upon the market at a price and sufiiciently proof against disarrangement of its parts as to insure its domestic use.

Referring now to the drawings forming a portion of this specification. and in which like numerals of reference indicate similar parts 1n the several vlews, Figure 1 1s a side elevation of amechanism embodying the present invention. Fig. 2 is a top plan view. Fig; 3 is section on the line 33 of Fig. 2,

with parts in elevation. Fig. 4 is a section on theline it-4; of Fig. 3.' Fig. 5 is a section on theline 5-5 of Fig. 3. Referring now to the drawings, the present apparatus'comprises an outer vessel 1') of cylindrical form and having at its upswer edge an inwardly curled bead 11, for purposes to be presently explained. In conncction with the vessel there is employed a second cylindrical vessel 12 which in practice is disposed centrally of the vessel 10 and is held in such position by. means of a pair of angular brackets 13 each of which comprises a finger 14 which radiates from the vessel 12. These brackets are riveted or otherwise secured to the vessel 12 at diametrically opposite points of its {upper edge portion and the extremities of the fingers 1i thereof contact with corresponding portions of the'inner face of the vessel 10 directly below the head 11 so that the head prevents upward disengagement of the fingers and corresponding displacement of the-inner vessel 12, it being understood that the vessel 10 is of a material that will permit it to be sprung so that this engagement of the fingers may be accomplished. To prevent rotation or lateral displacement of the vessel 12 within the vessel 10, each of the fingers 14 is provided with a lug 15 which is engaged in a corresponding slot 16 in the upper edge portion of the vessel 10.

In the practice of the'process above referred to, the butter and milk are agitated and commingled within the vessel 12,. to accomplish which result the following" de scribed mechanism is employed.

Upon the bottom of the vessel 12 is secured a radial plate 17 having a bearing socket 18 located centrally of the vessel 12 and having at its extremity against the wall of the vessel an angular socket 19. In the angular socket 19 is received the correspondingly shaped foot of an upright 20 having fingers 21 that extend radially of the vessel 12 1n parallel relation as illustrated. The foot of the upright 20 is removably engaged 1n the socket 19 and to hold the upright in erect position its upper angular end 22 is engaged in a radial slot 23 formed in the cover 24: that is provided for the vessel 12, said cover including a depending flange 25 which engages snugly within the upper portioa of the vessel 12 and is'cut away as shown at to 'cotrespond to the slot.23 in the top portion of the cover. The slotted portion of the top member of the cover 2 1 projects slightly beyond the outer wallof the member 12 so as to receive in its slot an upwardly pro ecting lug 27 formed on one of the brackets 13. The lug 27 thus holds the cover from rotating on the vessel 12 and the cover in turn til-1) holds the upper end of the upright 20 against displacement. ,'llie upper end portion of the upright. 20 is flanged as shown at 28 directly beneath the cover 24 to prevent upward displacement of the upright from the socket 19. v In connection with the fingers 21, which are battles, there is employed a stirrer or dasher including a shaft 29', having fingers 29"and 30 that radiate respectively from diametrically opposite sides of the shaft 29,

' "each finger 29 being in the same plane with a corresponding finger 30 and both the fingers 2%) and 30 being spaced apart the same distance as are the fingers 21 but alternating in elevation therewith so that'as the dasher is rotated, the fingers 29' and 30v will move between and out of contact with the fingers 21. The lower end of the shaft 29 has a bearing in the socket 18 while its 20 upper end is provided with a frusto-pyramidal enlargement that snugly engages a corresponding central opening in a bevel pinion 31 having a depending stub sh ft 32 .that rotatablyengages within a' flange 2-5 that circumscribes a central opening 34 in the cover 24. By reason of the frusto-pyramidal shape of the enlargement 30, it ermits of instant removal or application 0 the pinion 31 with respect thereto and of the 30 cover 24 with respect to the vessel 12 and to prevent accidental removal of the pinion from the shaft 29. and the flange of the cover, there is provided a keeper which supports also a handle for steadying the appa- 35 ratus during the operation. The keeper comprises a pair of arms 35 and 36 which adjacent their mutual upper end connection 37 are parallel and below which parallel por tions they diverge downwardly as shown at 38 and 39 and are then extended in opposite directions in a common plane to form feet 40 and'41 which are slotted as shownv at 42 to receive bolts 43 through the medium of which they are securely fastened against the 45 upper face of the cover 24 and with the portions 38 and 39 straddling the pinion 31 in such close relation thereto as to prevent upward movement of the pinion to a degree sufficient to permit of its removal from the flange 33. From the connecting portion37 of the members 35 and 36 there is an upward extension 44 with which is engaged a horizontally lying handle 45. l

T'o rotate the pinion 31 and therewith the stirrer or dasher, there is employed a bevel gear wheel'46 including a hub 47 having a central cross sectional y angular passage which is shaped to snugly receive the frustopyramidal enlargement 48 formed upon a crank shaft 49 having a bearing in the open topped journals 50 formed in the upper ends of posts 51 and 52 formed upon the cover 24. The post 52 is so positioned that when the gear 46 is 'in mesh with the pinion 31 the end of the hub 47 at the minor end of its axial 7 passage will rest against th'e'post 52 so tha. movement of the gear from engagement with the pinion will be prevented, lpngitudinal movement of the crank shaft 25 in the cor:- responding direction being otcourse prevented by the corresponding tapers of the hub passage and the enlargement 48. Longitudinal movement of the crank shaft in the oppo-' site d rectlon is prevented by the circumscribing flange 53 on the shaft which bears against the-inner face of the post 51. Upward displacement of the crank shaft 49 from its bearings is prevented by the portion 37 of the combined handle support and pinion keeper hereinafter referred to, said portion 37 passing over and in close relation to the crank shaft. y y

In the use of the present apparatus, equal parts by weight of butter and milk are" placed withinthe receptacle or vessel*12,the butter in a more or less soft state to facilitate its passage between the fingers21 of'the baflle and the milk, cold or at a temperature of about 50 degrees. Water ata temperature of from 100 to 110 degrees Fahrenheit is then placed in .the vessel 10 in quantity sufiicient to stand at a height somewhat above the contents of the vessel 12, the rela tive proportions of the vessels being substantially those illustrated. The crank shaft 49 is then rotated through the medium of its handle, first slowly to make sure that the contents of the vessel 12 are in such a state as will insure their passage between the fingers of the battle and the dasher, and then at a speed of about 120 revolutions per minute.

At the end of about three minutes it will be found that the milk has entirely merged into the butter in the form of an emulsion. it is desired to color the product, the proper added and the apparatus operated. sulficiently long rio mix the coloring matter thoroughly through the product.-
